[jdk20] RFR: 8299862: OfAddress setter should disallow heap segments

Tue Jan 10 14:12:06 UTC 2023

When unifying memory address with memory segments, we missed the case where a heap memory segment is passed as a value to a var handle address setters.

The solution is to reuse the same check we use when validating segment downcall parameters also for segment memory writes.
